' v `soumis.' (ol. 229-14) This invention relates to shipping containers and aims, among other objects, to provide `an improved, durable container having la moistureproof reinforcing lining, the inner faces of' which are sanitary, moisture-proof 'and pleasing in appearance. v p In the drawings showing the preferred embodiment of the inventionr-f Y Fig. 1` is a perspective View of the container lo in open position; Y

In shipping various commodities, and more especially dressed poultry, it is highly desirable that a strong moisture-proof, sanitary container be used. The present invention provides alight weight, durable container made oi. corrugated ber board having a lining of 'similar material, whose inner surfaces are both moisture-proof and pleasing in appearance. When poultry `are tightly packed in a box breasts up, the breasts are squeezed into narrow triangular' form. Poultry heretofore have been packed in Wooden boxes, the idea being te nail the lids down tight,

so thatthe breasts are nattened toa certain extent to make a better appearance for the market. In all previous attempts to use corrugated fiberboard boxes, there was not the strength in the 40 box by virtue of its construction, to ilatten Vthe breasts. In the present container,` however, lby the force which may be applied in shutting the lid and by the vleverage pressure placed on the top of the linen'which is in direct contact withl the breasts, it is possibleto ilatten the breasts.

y p0 sold, the next prospect at once sees from the condition of the box that someone has rejected it (although the rejection may be solely because of personal prejudicey nearly all poultry being packed in accordance with U. S. Standards) and therefore may not want to buy it. With the improved corrugated box, it may be opened, and, I l if the prospect declines to buy, the box may be closedjand no one can tell that it has been opened before, because it is not necessary to seal the box in any Vmanner, except to guarantee against pilfering. This can be done by placing a single small seal over the joint at the front of the box.Y 'W 1 The greatest difficulty in the use of corrugated fibre boxes with refrigerated food products is that the moisture breaks down the Walls of the corrugations. Naturallythis moisture is most destructive where the open corrugations are exposed. `The presentfbox is so constructed that there isno point where the corrugations are exposed that has any vital bearing on the strength and durability of the box.` All parts of the box which must bear the weight and'hold up under usage, `and have open corrugations, are covered with other layers of corrugated board. v

Referring'particularly to the v,drawings'lthe improved container is shown ascomprising a folding box 10 havingva two-piece lining, one piece 11 forming a ,reinforced front, rear and end wallsand thei other piece `12 forming reinforced 90 top, bottom, front and rear Walls. v

The body of the box10 is'preferably formed yfrom a single sheet of corrugated board which 'is vand 148 Vand end Walls 19 are bent upwardly at rightangles to the bottom andr the end naps 20 are thenbent inwardly at right' angles to the 95 walls 17 and 18. The flaps 20 are secured tor- `gether by` suitable fastening `means, such as staples 24'. The lid naps 22 and 23 may then be bent inWa-rdlyfat right angles to the lid y21 and when desired the lid may be folded down to close the box, the score line between the lid and the wall 18 acting as a hinge.

It will be noted in Fig. 1 that when the box is set up, the connected end flaps 20 and also the front wall 17 are arched outwardly to provide a ,1 05 resiliency which will tend to protect them from injury should they be struck a blow during handling of the box. This construction also more readily permits the insertion of the naps 22 and 23. The naps 23 are inserted in the spaces be- .1010

tween the end flaps 20 and the ends 19, as shown in Fig. 2, and the flap 22 is inserted between the front wall 17 and the front wall of the liner 12, which will be later described. The adjacent corners of the flaps 22 and 23 are cut off to facilitate further the closing of the lid.

The parts 11 and 12 forming the reinforcing liner for the box are each made of a corrugated fiber board and scored to be folded to fit the inside of the box. The part 12 is bent to form a bottom portion 25, which covers the entire bottom of the box; a front wall 26 integral with the bottom 25; a top 27 integral with the wall 26, and a rear wall 28 constituting a flap which is integral with the top 27.

The part 11 is bent to form end walls 29 and front and rear walls 30, the open joint being .at one corner. The material forming ,part 11 is preferably double corrugated board with the corrugations extending vertically, as shown, to give the container the desired vertical strength. The Walls 29 -abut the inner faces of the walls 19 of the box while the walls 30 abut the inner faces of the walls 26 and 28.

It will be noted that the corrugations are so arranged that moisture cannot enter their open ends. The corrugations on the bottom 16, walls -17 and 18, top 21 and flap 23 extend longitudinally of the box; on walls 19 and naps 23 they extend vertically; and on flaps 20 they extend transversely. On the walls 29 and 30 of part 11, the corrugations extend vertically; on the top 27 and bottom 25 vof part 12 they extend transverse- 1y; and on walls 26 and 28 of part 12 they extend vertically.

Thel ends of the corrugations on walls 29 yan 30 are closed by the top 27 and bottom 25; on walls 19 they are closed by the lid 21; on wall 28 by bottom 25; and .on bottom 25 by wall 18. The only corrugations open to moisture are those on the ends of flaps 20v and at the edges of flaps 23 and these points have no vital bearing on the strength of the container. Moreover, by arranging the corrugations in this manner, all of the six sides of the container are composed of several thicknesses of material. the corrugations of which extend at rightangles to each other, thereby providing a very strong and durable container.

To make. the container both sanitary and pleasing in appearance, the inside faces of the liner parts 1l and 12 are treated to provide a white, moisture-proof surface. When the containers are opened, the contents are displayed against a clean white background which tends to promote sales.

When the container is set up, the box 10k is first assembled, the bottom 25 of the liner 12 is then placed on they bottom 16 with the wall 26 at the front of the box and the top 27. hinged out- Vwardly from the wail 2,6. The liner 11 is then placed in the box on bottom 25 and, after the yil' desired. To assemble one requires very little time as it is only necessary to bend the several blanks on the various Score lines and fasten the flaps 20 together by a couple of staples 24 which can be very easily applied with an ordinary hand stapling machine.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described.

What I claim isz-- 1..A shipping container comprising, in combination, a box formed of corrugated fiber board and having a bottom; front, rear and end walls integral with the bottom and bent upwardly therefrom; end flaps integral with and bent inwardly from the front and rear walls and secured together; a lid integral with the rear wall; ymarginal end and front flaps integral with the lid, said lid and flaps being insertable between the end walls and the end flaps, said lid front flap being insertable behind the front wall; a lining element having a bottom and a front wall integral with the bottom and abutting the rear face of the lid front iiap; said element having a top integral with the front wall and a rear wall integral with the top; and a second single piece lining element bent to form front, rear and end walls extending between the top and bottom of the first lining element.

2. A shipping container comprising, in combination, a box formed of corrugated ber board and having a bottom; front, rear and end walls ,c integral with the bottom and bent upwardly T29 therefrom; end flaps integral with and bent inwardly from the front and rear walls and secured together; a lid integral with the rear wall; marginal end and front flaps integral with the lid; the corrugations of the end walls extending vertically and being closed at their upper ends by the lid; a one-piece lining element in the box made of corrugated board and bent to form a bottom portion, a top portion, and front and rear walls; and a second oneapiece lining element made of double corrugated board within the rst lining element and bent to form front, rear and end walls.; the corrugations of the second lining element extending vertically and being closed at their upper and lower ends by the top and bottom of the rst lining element.
